When closure set dust hood 113 under this state, the upper end of scotch 90 will be positioned on the track of the bottom that locks teat 93.Promptly, when in dust storage chamber 109, not accommodating dust collect plant 107, and when fixedly dust gathering arrester 113 being closed under the state of the cardboard 40A of disposable filter 40 on locking component 41, the lower surface of locking teat 93 contacts by the upper surface with scotch 90, will stop dust gathering arrester 113 to be closed.Front end and rear end in the upper surface of scotch 90, be formed with outstanding upward projection 95 respectively, even under the upper surface state of contact of lower surface and the scotch 90 of locking teat 93 when dust gathering arrester 113 further applies power to closing direction, also can utilize projection 95 to stop the situation that teats 93 are crossed to the front side or the rear side of scotch 90 that locks.
Figure 23 is the profile of seeing along the E-E line shown in Figure 21, and the state of disposable filter 40 has been installed in expression.
Scotch 90 is positioned at the insertion path of the cardboard 40A of disposable filter 40, when disposable filter 40 is installed, in the process that cardboard 40A is slided downwards along guide member 46, the front of cardboard 40A will with the back sliding-contact of scotch 90.Like this, in the process that disposable filter 40 is installed, scotch 90 is used to the active force from disposable filter 40 (cardboard 40A), will be from the position shown in Figure 22 (primary position), and the elastic force of resistance compression helical spring 94 and rotating to clockwise direction.In addition, as shown in figure 23, under the state that disposable filter 40 has been installed, the back of scotch 90 all contacts with the front of the cardboard 40A of disposable filter 40.Under the situation of under this state dust gathering arrester 113 being closed, the lower surface of locking teat 93 can not contact with the upper surface of scotch 90, and admissible set dust hood 113 is closed.
The profile of the section when Figure 24 is see from the top this electric dust collecting apparatus 101C is cut open with horizontal plane, the state of dust collect plant 107 has been installed in expression.In addition, Figure 25 is the profile of seeing along the E-E line shown in Figure 24 1, and the state of dust collect plant 107 has been installed in expression.
As use Fig. 8～Figure 10 explanation like that, at the side (right-hand) of the inlet 50 of the front of dust collect plant 107 (outer cover 52), the outstanding fin 72 that is formed with along the vertical direction (the dismounting direction of dust collect plant 107) extension towards the place ahead.Scotch 90 is positioned at the insertion path of the fin 72 of dust collect plant 107, when dust collect plant 107 is installed, in the process that dust collect plant 107 is slided downwards, the end surface of fin 72 (front end face) will with the back sliding-contact of scotch 90.Like this, in the process of dust collect plant 107 was installed, scotch 90 was used to the active force from dust collect plant 107, will be from the position shown in Figure 22 (primary position), and revolt the elastic force of compression helical spring 94 and rotate to clockwise direction.In addition, as shown in figure 25, under the state that dust collect plant 107 has been installed, the end surface of the fin 72 of dust collect plant 107 all contacts with the back of scotch 90.Under the situation of under this state dust gathering arrester 113 being closed, the lower surface of locking teat 93 can not contact with the upper surface of scotch 90, and admissible set dust hood 113 is closed.
